With ecoHeat on, the Passiv Smart Thermostat will optimise your heat pump to maximise comfort and minimise costs.
With ecoHeat off, your heat pump will only run to meet your temperatures within scheduled heating periods. With ecoHeat on, your heat pump will run earlier to make sure that your target temperatures are reached by the time your scheduled period starts.
Despite running longer with ecoHeat on, your heat pump actually uses less energy. Running at lower temperatures for longer increases your heat pump’s efficiency, meaning it outputs more heat whilst using less electricity. The Passiv Smart Thermostat calculates the best compromise of minimising costs whilst still ensuring comfort.
ecoHeat also allows you to optimise your heat pump to time-of-use tariffs. If you have a tariff with multiple rates across the day, you can input that tariff using the Passiv App. Your heat pump will then run at times of the day where electricity is cheapest whilst still maintaining target temperatures.
